Job description

Tagup is a defense technology company founded at MIT that is redefining logistics superiority with next-generation AI. We’re growing rapidly and are looking for change-makers passionate about delivering innovative technologies to solve the most challenging problems in the world’s highest stakes environments. This is an exciting opportunity to engage in meaningful work that strengthens national security and contributes to the success of U.S. and allied forces. Join us in shaping the future of defense logistics for a safer tomorrow.

As a Full-Stack Engineer, you’ll own features end‑to‑end—turning user needs into intuitive React interfaces, well‑designed APIs, and reliable data models. You’ll work closely with product, design, and data partners to scope, iterate, and ship quickly, balancing speed with maintainability and security. Your work will be measured by the outcomes you deliver for users in high‑stakes, real‑world environments.

What You’ll Do

• Own features across the stack—from React UI to APIs, data models, and pipelines that feed AI-driven capabilities
• Build intuitive, performant web experiences; translate wireframes into accessible, production‑ready interfaces that handle large datasets
• Design, implement, and operate APIs and database schemas; write clean, well‑tested Python and SQL, including high‑performance queries
• Ship reliable software with unit/integration tests, CI, and thoughtful code reviews; uphold cross‑browser compatibility and front‑end performance best practices
• Deploy and run services with containers/orchestration (Kubernetes) and IaC (Terraform) on AWS; contribute to ETL jobs and data integrations
• Partner closely with product, design, and data teams to iterate quickly and deliver measurable outcomes for users

Required Skills

• 3+ years building production web applications across front‑end and back‑end
• Fluency in Python and SQL; experience designing and shipping REST APIs
• Strong React fundamentals (state management, async patterns, component design) and modern JavaScript/TypeScript (ES6+)
• Clear, pragmatic communication of trade‑offs; habit of writing clean, maintainable, well‑tested code

Bonus Points

• AWS and Terraform; Kubernetes operations
• Data visualization (e.g., D3, Vega)
• Robust integration and front‑end testing practices
• Networking knowledge
